- Achieves up to 30dB of terminal coupling loss [TCLwst] by adaptive means, without inserting any attenuation
- Convergence rate > 30dB/sec
- Robust double talk detection.
- Faster convergence time.
- Adjustable gain pads at Sin and Sout to compensate for different system requirements.
- Capable of handling speaker non-linear harmonic distortion.
- Suppresses highly non-linear residual echo without any perceptual loss.
- Control of Non-Linear Processor thresholds for suppression of residual non-linear echo
- Optional Comfort Noise Generation [CNG] attenuates residual echo to background noise level or user configured level.
- High pass filters at Rin and Sin for removal of DC components in PCM channels
- Availability of tuning parameters to optimize the algorithm performance for a system.
- Multi-channel Capability.
- Flexible Programming Interface [‘C’ Callable].
- Provided in the form of Hardware Independent Library for easy pointing to the target platform.
